Pathway Overview
12 steps
Algorithm Steps
12 total
01Start 02Action Diagnostic Criteria
Minimum criteria for empiric treatment
- MINIMUM CRITERIA (any one):
- - Cervical motion tenderness
- - Uterine tenderness
- - Adnexal tenderness
- ADDITIONAL CRITERIA (support diagnosis):
- - Temp >38.3°C (101°F)
- - Mucopurulent cervical discharge
- - WBC on wet prep
- - Elevated ESR or CRP
- - Lab evidence of GC or chlamydia
03Action Diagnostic Workup
Rule out emergencies, obtain cultures
- Pregnancy test (rule out ectopic)
- NAAT for GC and chlamydia
- Wet prep/vaginal microscopy
- HIV testing
- Consider: CBC, CRP, urinalysis
- Pelvic ultrasound if TOA suspected
04Decision Severity Assessment
Inpatient vs outpatient management
05Action Inpatient Criteria
Admit if any present
- Surgical emergency not excluded (appendicitis, ectopic)
- Pregnant
- Unable to tolerate oral meds (N/V)
- Severe illness, high fever, peritonitis
- Tubo-ovarian abscess
- Failed outpatient therapy
06Action Inpatient IV Treatment
Parenteral regimens
- REGIMEN A:
- Ceftriaxone 1g IV q24h + Doxycycline 100mg IV/PO q12h + Metronidazole 500mg IV/PO q12h
- REGIMEN B:
- Cefoxitin 2g IV q6h + Doxycycline 100mg IV/PO q12h
- Transition to oral after 24-48h improvement
07Action Follow-Up
Essential for all patients
- 72-hour follow-up for clinical improvement
- Partner treatment (expedited partner therapy)
- STI counseling and education
- Retest for GC/chlamydia in 3 months
- Counsel on fertility implications
08Outcome Resolution
Complete antibiotic course, test of cure
09Action Outpatient Treatment
CDC 2021 recommended regimen
- Ceftriaxone 500mg IM x1 (1g if ≥150kg)
- PLUS Doxycycline 100mg PO BID x 14 days
- PLUS Metronidazole 500mg PO BID x 14 days
- Alternative cephalosporin + probenecid options available
- Follow-up in 72 hours essential
- Path rejoins step 07Shared downstream outcome
10Warning Partner Notification
All sex partners in past 60 days
- Evaluate and treat presumptively
- Expedited partner therapy if allowed
- Abstain from intercourse until treatment complete
11Decision Tubo-Ovarian Abscess?
Ultrasound or clinical suspicion
12Action TOA Management
May require drainage
- IV antibiotics initially
- Consider interventional drainage if >6-8cm
- Surgical management if ruptured
- Follow with imaging for resolution
- May require prolonged antibiotics
- Path rejoins step 07Shared downstream outcome
